Resolved Caveats—Cisco IOS Release 12.0(28)S6
• CSCsb07807
Symptoms: A Cisco 10000 series unexpectedly drops some traffic after you have entered the no
service-policy policy-name policy class-configuration command.
Conditions The symptom observed when the policy that is removed is referenced in other policies,
such as in policy map “c” in the following configuration example:
policy-map p1
class class-default
shape 10000
service-policy c
policy-map p2
class-default
shape 20000
service-policy c
Workaround: There is no workaround.
• CSCsb11124
The Cisco IOS Stack Group Bidding Protocol (SGBP) feature in certain versions of Cisco IOS
software is vulnerable to a remotely-exploitable denial of service condition. Devices that do not
support or have not enabled the SGBP protocol are not affected by this vulnerability.
Cisco has made free software available to address this vulnerability for affected customers. There
are workarounds available to mitigate the effects of the vulnerability.
Cisco has published a Security Advisory on this issue; it is available at
http://www.cisco.com/warp/public/707/cisco-sa-20060118-sgbp.shtml
• CSCsb12969
Symptoms: All VIPs or FlexWAN modules reload unexpectedly on a platform that is configured for
Modular QoS CLI (MQC).
Conditions: This symptom is observed on a Cisco 7500 series (with VIPs) and a Cisco 7600 series
and Cisco Catalyst 6500 series (both with FlexWANs) when the following steps occur while the
physical interface is in the UP state:
1. An input policy and output policy map are already attached to an ATM or Frame Relay PVC.
When you attach the same policy map to the main interface, an error message is generated and
the configuration is rejected.
2. You remove the policy map from the PVC and attach the same policy map to the main interface.
3. You remove the policy map from the main interface.
At this point, all VIPS or FlexWAN modules reload, even though no traffic is being processed during
the above-mentioned steps.
Workaround: There is no workaround.
• CSCsb28139
Symptoms: An LDP/BGP adjacency is not formed, and a ping does not go through.
Conditions: This symptom is observed on a Cisco 12000 series that functions in a scaled VPN
environment when an Engine 6 line card faces the core of the MPLS network.
Workaround: Enter the clear ip route * command.
• CSCsb46607
Symptoms: A standby route processor (RP) may crash in the “CEF LC IPC Background” process.
